Abstract

Métodos y aparatos de procesamiento de imagen o video comprenden recibir datos de entrada asociados con una imagen actual o un segmento actual en la imagen actual, determinar si la imagen actual es una imagen monocromática, parámetros de desbloqueo croma de análisis de señalización dependiendo de si la imagen actual es una imagen monocromática, y codificar o decodificar la imagen actual o el segmento actual. Los parámetros de desbloqueo de croma se utilizan en una operación de filtro de desbloqueo aplicada a los componentes de croma de la imagen actual o del segmento actual cuando la imagen actual no es una imagen monocromática. Un elemento de sintaxis puede utilizarse para indicar derivación de los parámetros de desbloqueo de croma, y con base en un valor del elemento de sintaxis, los parámetros de desbloqueo de croma se permite que sean señalados de manera explícita o analizarse desde una estructura sintáctica, o se infieren de manera implícita los parámetros de desbloqueo de croma.
